New Unifrog version replaces both SL-8381 Insulfrog and SL-E8381 Electrofrog with a new and improved design that can be used either way.

83 Line items are realistic models of North American railroad track, with Code 83 nickel silver rail. Scaled from A.R.E.A. drawings and NMRA compliant, Code 83 features authentic tie sizes and spacing, the standard American number system for frog geometry, plus a very fine representation of traditional rail spike fixings.
